Our payment system change window is 10 p.m. to 2 a.m. The plan is 90 minutes to deploy and 30 minutes of smoke testing. Rollback takes 60 minutes, plus 30 minutes to verify afterward. Deployment ran 50 minutes late. How do you decide whether you can still continue?

支付系统变更窗口是晚上 10 点到凌晨 2 点。计划部署 90 分钟、冒烟测试 30 分钟，回滚要 60 分钟，回滚后验证还要 30 分钟。结果部署拖了 50 分钟才完成，你怎么判断还能不能继续？
